Tissue engineering bone provides a new method for the rehabilitation of bone defects which are caused by tumor resection,trauma and inborn deformity. How to find the cell seeds is the key problem of the bone tissue engineering.We chose bone marrow stromal osteoblast cells as cell seeds in this study.These cells were cultured in vitro to construct bone marrow stromal osteoblast cell sheet.A new method for constructing polimer of bone marrow stromal osteoblast cell----Bone marrow stromal osteoblast cell...
